Detailed Description

template<typename T, class BinaryOperation, int Dims, size_t Extent, class Algorithm, bool View>
class cl::sycl::ext::oneapi::detail::reducer< T, BinaryOperation, Dims, Extent, Algorithm, View, enable_if_t< Dims==0 &&Extent==1 &&View==false &&IsKnownIdentityOp< T, BinaryOperation >::value > >

Specialization of the generic class 'reducer'.

It is used for reductions of those types and operations for which the identity value is known.

It allows to reduce the size of the 'reducer' object by not holding the identity field inside it and allows to add a default constructor.
